Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] See also Figure 1-5 A wireless constant torque electric gun that is easy to store includes a battery base 1, a grip rod 2 is clamped on the top of the battery base 1, a wiring assembly 3 is provided inside the grip rod 2, the wiring assembly 3 includes a clamping post 301 rotatably connected to the inside of the grip rod 2, a wire 302 is wound around the outer end of the clamping post 301, one end of the wire 302 is fixedly connected to a wiring head 303, a clamping hole 304 is provided on the top of the battery base 1, the wiring head 303 is clamped inside the clamping hole 304, a gear 305 is fixedly connected to the outer end of the clamping post 301, the gear 305 is rotatably connected to the inside of the grip rod 2, and a first torsion spring 306 is fixedly connected between the gear 305 and the grip rod 2. The purpose of this arrangement is that the wire 302 arranged inside the handle 2 is convenient for connecting the handle 2 with the battery base 1. When working at a height, the battery base 1 can be placed on the top of the tripod to reduce the weight of the handle 2, making the staff more comfortable during operation and reducing the staff's workload. At the same time, the first torsion spring 306 is arranged so that the gear 305 drives the wire clamping column 301 to drive the wire 302 to always be in a straight state, thereby preventing the wire 302 and the tripod from being entangled with each other during operation.

[0025] Preferably, a storage groove is provided at the bottom of the grip 2, the wiring head 303 is arranged inside the storage groove, the wiring assembly 3 also includes a card plate 307 slidably connected to the inside of the grip 2, the outer end of the card plate 307 is rotatably connected with a clamping tooth 308, the clamping tooth 308 is meshed with the gear 305, a limiting groove is provided inside the card plate 307, the inner wall of the limiting groove is arc-shaped, the clamping tooth 308 is teardrop-shaped, the inside of the grip 2 is rotatably connected with a limiting roller 309, and the wire 302 is clamped with the limiting roller 309. The purpose of this setting is that the storage groove inside the card plate 307 allows the clamping tooth 308 to rotate only counterclockwise, thereby preventing the staff from resetting the wire 302 by the clamping column 301 during operation, thereby preventing the wire 302 from winding up.

[0026] In this embodiment, when the staff needs to work at a height, the battery base 1 is removed from the bottom of the handle 2 and placed on the top of the tripod, and the wire 302 inside the handle 2 is pulled out. When the wire 302 is pulled out, the wire clamping column 301 rotates inside the handle 2. As the gear 305 rotates, and due to the limiting groove at the outer end of the clamping plate 307, the clamping tooth 308 can only rotate counterclockwise, so that the clamping tooth 308 rotates, thereby preventing the wire clamping column 301 from rotating and resetting, thereby preventing the stretched wire 302 from winding up and affecting the normal use of the equipment.

[0027] Embodiment 2:

[0028] See also Figure 1-6 This embodiment provides a technical solution for a wireless constant torque electric gun that is easy to store on the basis of the first embodiment: a push rod 4 is fixedly connected to one side of the card plate 307, a positioning plate 5 is fixedly connected to the inside of the grip 2, the push rod 4 and the positioning plate 5 are slidably connected, a clamping plate 6 is fixedly connected to the outer end of the push rod 4, a tension spring 7 is fixedly connected between the positioning plate 5 and the clamping plate 6, a button 8 is fixedly connected to the outer end of the push rod 4, and the button 8 is slidably connected to the grip 2. The purpose of this arrangement is that when the wire 302 is recovered, the button 8 is pressed, and the button 8 drives the card plate 307 connected to the push rod 4 to slide inside the grip 2, so that the locking tooth 308 is out of position with the gear 305. At this time, the first torsion spring 306 drives the wire clamping column 301 at the outer end of the gear 305 to rotate and reset, thereby reeling the stretched wire 302.

[0029] Preferably, the top of the grip 2 is fixedly connected to the stun gun head 9, the outer end of the stun gun head 9 is symmetrically fixedly connected to the side plate, and the two side plates are fixedly connected to the pull rod 10. The purpose of this arrangement is that the pull rod 10 is convenient for the staff to operate with both hands.

[0030] Preferably, the bottom of the battery base 1 is fixedly connected with an upper connecting plate 11, the interior of the upper connecting plate 11 is rotatably connected with a lower connecting plate 12, a second torsion spring 13 is fixedly connected between the upper connecting plate 11 and the lower connecting plate 12, and a clamping claw 14 is fixedly connected to the inner side of the upper connecting plate 11 and the lower connecting plate 12 and the positions are corresponding. The purpose of this arrangement is that the clamping claw 14 on the inner side of the upper connecting plate 11 and the lower connecting plate 12 can be clamped on the side end of the tripod, thereby fixing the battery base 1 to prevent the battery base 1 from falling during the operation process.

[0031] In this embodiment, when the staff is working at a height, the clamping claws 14 that are aligned with the upper connecting plate 11 and the lower connecting plate 12 can be clamped on the side end of the tripod to prevent the battery base 1 from falling from the top of the tripod during work. When recovering the wire 302, press the button 8 at the outer end of the grip 2, and the button 8 drives the card plate 307 connected to the support rod 4 to slide inside the grip 2. At this time, the card teeth 308 inside the card plate 307 are out of position with the gear 305. At this time, the first torsion spring 306 drives the wire clamping column 301 to rotate and reset, thereby recovering the wire 302.
